` The Schedule referred to in these Letters Patent and making of the same.

Be it known that I, JosIAH S; CLARK, ot' the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Device for Mak` ing Connections of Lateral Branches to Pipes; for Conveying Fluids; and I do hereby declare the following to be a full, clear, andexact description thereof', reference being had to the accompanying drawing and y let-ters of reference markedthereon.

i The nature of `my invention consists .in so constructing a clamp, `with a suitable outlet vfor `attaching pipes or cocks, as to securely hold a tight joint upon thcpipe to which it is applied, and at the same `time avoiding any diminution in the strength of the tube at the place of attachment, the whole being so constructed as to be easily applicable, by persons of moderate mechanical ability,to pipes 'which may be omewhat irregular in the form of their external suraces.v i

. The precise mode of making and usingthis invention is hereinafter explicitly described, and shown in the several gures referredto in this specification. 1 i

The same letters of reference apply to thesame parts in the several figures. 1

Figure 1 shows a plan of this invention, as applied i to a vertical water-pipe;

Figure 2 shows a side elevation;

Figure 3 showsati'out elevation Figure 4 shows a vertical section;

`Figure 5 shows aholigontal section; Figpre 6 shows the back or rigid clamp in elevatio i 1 Figure 7 shows theiback clamp in horizontal sectiong Figure 8 shows the front` or flexible clamp in elevation; y

Figure 9 shows the front clamp in horizontal section; and l Figure lishows the packing or gasket. The back clamp A is made rigid by means of a rim,`B, formed on the back:`of it, and is grooved on the front vertically at C, sc as to receive and support I them and the'neck Q, hereinafter described.

The front or iexibleclamp K is made ot' ductile or flexible metal, and grooved` at L, so as to lit ap@ proximately over the pipe D, and has in the center ot' it a slot, P, parallel with the the groove L, which slot P has a rim, M, raised around it in the groove L, suiiicient in height to extend, through the gasket N, into the aperture O in the pipe D.

Upon the outer side of the clamp K is formed a short tube or neck, Q, screwed either internally or externally, or both, for the attachment of pipes or Stopcocks, and made dat at the point of' attachment tothe clamp K, so as not to stiften the clamp K at that point.

At a little distance from, and parallel with, the rim M, I form a little ridge, R, which, by inden'ting the packing or gasket N, renders a tight joint almost inevitable.

This short tube or neck Q communicates, through the' slot P and aperture 0, with the interior of the pipe D. In applying this invention to a pipe already erected, I place vbehind the vpipe the rigid clamp A, and secure itin. position by nailing or screwing it in such position that the pipe D lies fairly in the groove OL I next, with suitable implements, cut a slot in the frontof the pipe yD, of such size as to permit 'the rim M to tit in it. Themafter placing the gasket 'N 'arouud the rim M, I apply the clamp Kto `the pipe, so that the groove L'its over the pipe, and

the rim M iits into the aperture O, and vthen insert the screws G G,'through the slot-holes H H .in the flanges of the clamp K, into the holes F'F.

I tighten the screws until the gasket N is applied closely to the pipe, and the clamp K, being oi' `iexible material, adapts itself to. the form of the pipecD. s The rim M prevents -the pressure employed in clamping the .pipe D from collapsing the aperture O in the pipe, and isalso useful in retaining the gasket N in position when applying the clamp K to the pipe.

The advantages obtained in the use of this invention, as compared with other known modes of mak:

ing lateral branches to water-pipes, are, that less preparation is requisite to apply this apparatus; that very little skill is required in using-it; the strength .ofthe pipe is unimpaired at the place of the attachment, and the clamp K, by reason of its ilexibility, adapts itself to any slight variations in size or shape of the pipe I).

The flanges III are inclined forward, as shown in dotted lines in iig. 5, before the screws G G arey drawn up. Y

The slot-holes -H H facilitate the bending of the i clamp K.

I am aware that several devices, consisting of rigid ible, with a. flattened tnbulare or neck formed on it, the clamp-boxes, have been' used for making lateral atwhole being applied with a gasket, and secured by tachments to pipes. These, therefore, I distinctly screws to a tube, as shown and described. disclaim; but JOSIAH S. CLARK.
